supporting evidence• China is near ocean, and there is river in China. sometimes flooding can come from ocean and river.• South china is close to the equator. Lot of hurricanes happen near the equator and this can cause flooding happen.1/16/2013
Prevention• Bunds- large hole on the ground for stop water• Reservoirs-storage pond• Weirs-Separated by a river designed to change the flooding flow
Conclusion• Flooding is too much water from the river, ocean, and rain. At south China have many Flood happening every year, the evident for too many flood, is the weather is warm, and at my graph China 1991-2010 the flood is change too much. It is easy to have hurricane, and I see the people throw many garbage at the drainage channel At China. This make the drainage channel broken, this make the water can’t go to ocean and river. This cause the flood happen. If this pattern continues for the next 100 years, it would make the environment became very bad. The water is not clean because the garbage is everywhere, and everytime precipitation happen will cause flood.
